IMPROVEMENT 1N wAEP- DEEssEEs ...up Stimuli icrfm'ex tu in there itam what uns making 'part nf mesma 'ro- ALL seasons 2To jwHoM THESE PRESENTS' MAY COME:

)Be it known that I, BENJAMIN SAUNDERS, of Nashua, inthe county'of Hillsborough, and State of New Hampf `shire,"hav e'invented a new and useful Improvement in Warp-Dress`ersg and do hereby declare the same to be,v

" .fullydes'cribed inthe following specific-ation, and represented in the accompanying drawings, of which- Fgure'l'is a top view,

"Fignre 2 aside elevation,

Fgure avertical and longitudinal section, and

--l'Fiure 4 a. transverse section of a warp-dresser having my inventionl applied` to it. V The purpose of'suchinvention isto cause the sizing-brush frame to -operate with'little or no jar or undue vibration; 4', Y t

,Inl th e d rawings, A denotes the dresser-frame, B B the warp-beams or rollers, C C the warps, and D D',

E E" the. guiderollers o f such warps. F is the brush-frame, carrying two brushes, a a.1 The vertical side-bars,

b b, ofsueh frame, F, are supported at 'their ends on four bell-cranks, c, of Ktwo horizontal and parallel shafts;

whichare'duly sustained in bearn'gsf, and are arranged inmanner as represented. i r A driving-wheel or pulley, g, is xed on the front end of each of the said shafts. .An endless band onoord,

h, travels about lthe two wheels g, and serves lto transmit movement-from the lower to the Aupper of them. A -driving-pelley, z', is fixed on the middle of the lower shaft, andis to' be-,revolved bya band duly applied to it`. ,When such pulley, is in revolution, it will revolve the lower shaft, which will impart to the brush-frame its `proper motions, relatively to the warps, so as to cause the brushes to act on them in the desired manner. v

Y In' carrying out my improvement, I connterbala-nce the brush-frameand its 'cranks by means of weights ll,

' applied to the driving-pulleys, o r by making each of. such pulleys heavier en on'e side than on the other. In

iig. 1, the balanengweight of the upper pulley q is shown at'l, ani-nner side -view of such pulley being reprefsented in Figure 5` lZlhe lower pulley g is made like the upper ne, and provided with such'a counterbalaneeb l Y weight,

Thed'riving-'pulley of the lower` shaft may. also have holes made through it, on one sdeof teeentre, so

as to render it heavier on the other side, the holes being 'ai-ranged on the same side ofthe centre or axis as'the cranks are, the-whole being, with-the weights of vthe other pulleys, to effect the counterbalancingofthe brush frameand its operative cranks and brushes, i v

have found that when the brush-frame and its operative cranks are so countmbalaneed,l iis-will work very smoothly, and'with little or 'no noise or undue vibration, such as will shake the frame of the dresser, as results when the parts are not'coun'ter-balanced. Furthermore, that small bands'or cords only are necessary to eect v theV movements' of thepulleys of the brushframe`shafts, whereas, without the eonnterbalancing mechanism,

very short and wide belts'become requisite. I 4 i t 1I claim, in a dresser-frame, the combination of th'o counterhalance with the brush-frame, its operative .cranks and pulleys, as described. I

t BENJAMIN SAUNDERS.
